Erlang Capacity of a Voice/Data Cellular CDMA Uplink System Using Prioritized Admission Control and Adaptive Power Control

摘要

A CDMA ulpink system that carries both voice and data traffic is investigated. The reservation- based admission control scheme is used to prioritize voice mobiles, and the truncated channel inver- sion power control scheme is used by data mobiles to improve system capacity. The performance of the system is measured by the Erlang capacity Two methods of determining the Erlang capacity are presented. The first method decouples the analysis of blocking and outage performance, thus simplifying numerical search.
